Abstract
The utility model relates to a clean water circulating quenching device of a steel tie rod and belongs to the technical field of steel tie rod processing devices. The technical scheme is that the clean water circulating quenching device comprises a thermal treatment cooling medium tank (1), a cooling tower (4), a circulating water pipeline (3), a circulating water control valve (2) and a circulating water pump (5), wherein the thermal treatment cooling medium tank is connected with the cooling tower through the circulating water pipeline, and the circulating water control valve and the circulating water pump are arranged on the circulating water pipeline. The clean water circulating quenching device has the advantages that by adding a circulating cooling system, water temperature of clean water is controlled to be within 40 DEG C, cooling water flows circularly, and therefore quenching cooling capability of the clean water circulating quenching device is improved. Quenching temperature and tempering temperature of workpieces are controlled and the integral mechanical property of the steel tie rod can meet 345-level, 460-level, 550-level and 650-level mechanical property requirements. Compared with photoacid generator (PAG) polyester aqueous solutions and quenching oil, the clean water circulating quenching device reaches and is even better in the thermal treatment mechanical property, further reduces maintenance cost, avoids environment pollution and improves safety.
Description
Technical field
